Seigniorage
Since the 50 State Quarters program was expected to increase public demand for quarters which would be collected and taken out of circulation, the Mint used economic models to estimate the additional seigniorage the program would produce. These estimates established a range of $2.6 billion to $5.1 billion. (At the end of the program, the Mint estimated the actual increase in seigniorage to be $3 billion.) The Mint also estimated the program would earn $110 million in additional numismatic profits. (The final, post-program estimate was $136.2 million.) The Mint used these estimates to support the proposed program, and the legislation enacting the 50 States Quarters program cited these estimates.
